Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces CJ/T 263-2007 "Corundum Microporous Aerator for Water Treatment". Major technical changes compared to CJ/T 263-2007
The following is as follows.
--- Increase or decrease some term terms, modify the term name and definition of the definition;
--- Increase the spherical crown corundum microporous aerator, modify the structure of the aerator structure;
---Modify and improve the size and deviation of aeration parts of different specifications;
--- Increase the physical and chemical properties of the check valve;
---Modify and improve the oxygenation performance index of the corundum microporous aerator series products;
--- Cancel the original "Quality Assurance" section, and incorporate the part that involves the installation requirements into Chapter 8;
--- Cancel the normative "Appendix A" and "Appendix B" in the original standard, and modify and improve "Appendix C" as the "Appendix A" of this standard.
This standard was proposed by the Institute of Standardization of the Ministry of Housing and Urban-Rural Development.
This standard is under the jurisdiction of the Municipal Water Supply and Drainage Standardization Technical Committee of the Ministry of Housing and Urban-Rural Development.
This standard was drafted. China Municipal Engineering North China Design and Research Institute Co., Ltd., Jiangsu Jingxi Environmental Protection Equipment Co., Ltd., Jiangsu Fei
